SPINDLE AND BEARING THEREFOR.

SPECIFICATION forming part of Letters Patent No. 253,078, dated January 31, 1882.

Application led May 2A3, 1881. (No model.) Patented in England March 17, 1880, in France September 28, 1880, in Belgium September 30, 1880, and in Germany October 3, 1880.

To all whom tt may concern:

Be it known that we, JAMES MARSH and JAMES ALVIN MARSH, residing at Ashton-under-Lyne, county ot' Lancaster, England, and

subjects of the Queen of GreatBritain and Ireland, have invented certain Improvements in Spindles and Bearings therefor, (for which we have obtained a vBritish patent, No. 1,152, March 17, 1880,) of which the following is a 1o specification. A

Our invention relates to the spindles einployed in spinning` and doubling fibrous materials, and to bearings for such spindles, and` has for its principal objects to obtain steadiness of action and thorough lubrication of the bearings. We mount the spindle in top and bottom bearings in the upper and lower ends off alongtubular bolster which is fixed in a bolstercarrier, and we apply a removable oilcup to zo the lower end ot' the bolster-carrier. The oil is lifted from the oil-cup to the upper bearing by meansY of spiral grooves, and, overflowing, returns outside the bolster to a channelin the bolster-carrier, whence it is returned by oil- 2 5 ducts to the oil-cup. We make the bolstercarrier with or without a settling-chamber. When long sleeves are used we form a bearing lined or covered with anti-friction metal for the lower end ofthe sleeve.

3o In the accompanying drawings, Figure l is a vertical section, showing a spindle mounted according to our invention; Fig. 2, a sectional plan on the line l 2, Fig. l, with the sleeve removed, and showing the bolster-carrier; Fig.

3, a detached view of the lower end ofthe bolster; Fig. 4, a-vertical section, showing a modication ot' the mounting shown in Fig. l; Fig. 5, a view ofthe lower end ot' the bolster with its shield; and Fig. 6, a view of the retaining- 4Q ring for the oil-cup, Figs. l and 4.

ln Fig. l, a is the bolster-carrier, which is formed with a collar to rest upon the rail b ot' the machine, to which the spindle is applied, and with a shank which projects downward through a hole in the rail, and is screw-threaded to receive a nut, c, wherebythe carrier is firmly secured in position. The carrier is bored to receive a tubular bolster, d, and the bore in the carrier is slotted, drifted, or grooved, so as to form oil-duets e e. The bolster is driven 5o tight into its place in the carrier, the lower end ofthe bolster projecting below the carrier. The bolster is bored nearly from top to bottom, and

at the bottom is formed a footstep-bearing for the spindlef. The top end of the bolster is bored to receive abush, g, of German silver or other suitable metal, such bush consisting of a thin shell formed by bending a piece of sheet metal into a cylindrical shape or otherwise suitably formed. Aspiralgrooveiscut through 6o the bush, or is left between the nearly-meeting edges ot" the bent metal, as indicated by the dotted lines. A spiral groove is also cut in the spindle. The portion of the spindle which extends between the bearing g and the footstep is tapered, the bore ofthe bolster being tapered to correspond. The lower endof the bolstercarrier is turned to receive an oil-cup, 7L, the mouth of which cupv is bored to t the said end, and is channeled to receive a steel rin g, j,which 7o is separately represented by Fig. 6. The said ring is sprung into the channel in the mouth ot' the oil-cup, and by clasping the end of the bolster-carrier keeps the cup in position. Airpassages i z' are drilled in the upper partof the 75 oil-cup, and a groove or slot, d', is also formed in the lower end ofthe bolster, where it enters the bottom ot' the cup, so as to allow the air to escape when the cup h is being slipped on.

A spiral slot is cut in the lower end of the 8o bolster, as seen in Fig. 3, which is an .outside view ot' such lower end, and on the bolster at this point is fitted a cylindrical metal shield,

o, which can be turned or slipped upon the bolster so as to cover the slot` to any desired eX- tent, Fig. 5. The oil in the cup passes through this slot into the interior ot' the bolster and lubricates the tbotstepbearing, and is also raised by the spiral groove in the spindle to the upper bearing. rI he spiral cut in the upper 9o bearing works the oil through until it overflows and runs into the recess in a receiver, 7c, which is turned in the upper end of the bolster-carrier. From the receiver lt, which performs the functions of a sediment-collector, the oilducts 95 c return the oil to the cup 7i.

In the drawings,`a long sleeve, l, is fixed upon the spindle; but for some purposes this sleeve would not be required or ashorter sleeve would be used.

The interior of the upper part or shoulder, k, of the receiver k is lined with a bush of German silver or other suitable metal, and the lower end ofthe sleeve is turned to lit loosely in this bush. When an excessive strain is put upon the sleeve by a tight band the end of the sleeve takes a bearing in the bush.

In Fig. 4 the bolster-carrier a is formed with a second oil-chamber, m, communicating with the chamber 7c. The oil overflowing passes first into the chamber lr, and thence into the outer chamber, m, where sediment is deposited, which sediment can from time to time be removedwithoutstoppiugthespindle. Fromthe chamberm the oil returns to the cup hthrou gh an oil-duct, e. The chamber m is furnished with a hinged lid, in order that oil may be supplied to the cup h without removiugit. The bolster is hushed at both ends, the spiral cnt in the lower bush lifting the oil to the upper bearing. The footstep is in a piece which is connected with the lower end of the bolster by means of arms n, so that there is a clear space for the admission of oil all around the end ofthe lower bearing. The steel ringjis sprunginto a groove, which is turned in the end of the bolster-carrier. Vhen an excessive strain is put upon thc sleeve l, Fig. 4, its lower end takes abearing upon the upper end ofa shoulder, k, which projects from the receiver 7c up within thelower chambered end of the sleeve and fits close around the bolster, its exterior surface being' covered with a shell of a suitable anti-friction metal.

To prevent the spindle from being lifted when doiiing, we arrange a stop, p, consisting in Fig. l of a pin and in Fig. 4 of a screw, a portion of the head of which overhangs a flange on the driving whirl or pulley; or, instead of this stop, we may spring a small ring, r, on thelower end ofthe spindle and below the bottom bearing, g', as shown in Fig. 4.

We claim as our invention- 1. The combination of a spindle, carrier, oilcup h, and footstep-beariu g, with a bolster having a bush, g, at its upper end, provided with a spiral slot, and having at its lower end an opening to admit oil from the'cup to the spindle above the bearin g, all substantially as set forth.

2. rlhe combination of the spindle, oil-cup h, and footstep-bearing, with bolster, leaving a communication between the oil-chamber and spindle, and a bolster-carrier provided with ducts e, and asediment-collector com municatingwith said ducts.

3. The combination of the spindle, bolster, and ootstepbearing,with oil-cup h, and carrier having oil-chambers 7c and m, and oil-ducts c, substantially as described.

4. The combination of the spindle, footstepbearing, bolster, and bearin g at the upper end of the bolster, with a sleeve, l, and whirl, and the carrier havin g a shoulder, 7c', provided with a. bushing for the sleeve to bear against, substantially as set forth.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
